Towering over the London skyline, the gleam of the Shard can be seen for miles around. When Western Europe’s tallest building, a 310 metre (1,016ft) vertical city of offices, restaurants, apartments and luxury hotel rooms, is officially inaugurated on 5 July, Britons can expect a spectacle: lasers and searchlights will striate the night sky as the London Philharmonic thrashes out the dramatic crescendos of Aaron Copland’s Fanfare for the Common Man.
